From the given alternatives, choose the one which best expresses the sentence in Active/Passive voice.
She makes cakes every Saturday

Cakes are made by her every Saturday

The correct answer is Cakes are made by her every Saturday.

The original sentence is in active voice, with the subject "she" and the verb "makes". To change it to passive voice, we make the object of the active sentence, "cakes", the subject of the passive sentence. The verb "makes" becomes "are made", and we add the preposition "by" to show who is doing the action. This gives us the passive voice sentence "Cakes are made by her every Saturday".

The other options are incorrect.

• Every Saturday cakes made by her is in passive voice, but it is not grammatically correct. The preposition "by" should not be placed before the subject of a sentence.
• Cakes make her every Saturday is not in passive voice. It is a sentence fragment that does not have a subject or a verb.
• Cakes were made by her every Saturday is in the past tense passive voice. This sentence is not appropriate for the original sentence, which describes an action that happens every Saturday.
